const promise = new Promise((resolve, reject) => {
    console.log(1);
    resolve();
    console.log(2);
    setTimeout(()=>{
      console.log(7);
    })
});
promise.then(() => {
    console.log(3);
    setTimeout(()=>{
      console.log(6);
    })
});
setTimeout(()=>{
  console.log(5);
})
console.log(4);

setTimeout (fn, 0) is executed at the beginning of the next event loop, and Promise.then () is executed at the end of the current event loop.
